Think about this.
Math is the least subjective thing to learn in school. It isn’t shades of grey. You can easily prove an answer us right or wrong.
Now think about something with some wiggle room in it. Some room for interpretation.
Like History. Or Ethics. Or Politics (Social Studies) or heck even Geography!
If the test is written by someone of a different opinion than you, those correct answers you give them could be “wrong” according to the test.
For example there is a huge historical debate over the “primary cause of the civil war.”
Slavery? States Rights? Economics?
Depends on who writes the test.
Common Core doesn’t leave room for debate, just tests.
And now even the right answer could be wrong just because they don’t bother to look it up!

But my daughter was right: if Curtis walked three miles a day for 26 weeks, Curtis did in fact walk…
